City manager Mark Rohr announced the number of known dead at a pre-dawn news conference outside the wreckage of a hospital that took a direct hit from Sunday’s storm. Rohr said the twister cut a path nearly 6 miles long and more than a half-mile wide through the center of town, adding that tornado sirens gave residents about a 20-minute warning before the tornado touched down on the city’s west side.

Much of the city’s south side was leveled, with churches, schools, businesses and homes reduced to ruins.

Fire chief Mitch Randles estimated that 25 to 30 percent of the city was damaged, and said his own home was among the buildings destroyed as the twister swept through this city of about 50,000 people some 160 miles south of Kansas City.

“It cut the city in half,” Randles said. (nearly 100 reported killed by the twister and unknown injured)

CNN) — A tornado flattened buildings, snapped trees and tossed tractor-trailers like toys as it touched down in Joplin, Missouri, on Sunday night, causing an unknown number of deaths and injuries. The hospital was hit too.

The twister was part of a line of severe weather that swept across the Midwest on Sunday, prompting tornado watches and warnings that stretched from Wisconsin to Texas. High winds and possible tornadoes struck Minneapolis and other parts of Minnesota, leaving at least one person dead and injuring nearly two dozen others, police said.
